The nutria (), an invasive alien species, is widely spread in Europe. Pursuant to regulation (EU) no. 1143/2014, the nutria is subject to management programs to reduce its spread. Surgical fertility control is considered an acceptable method, particularly in urban circumstances, avoiding euthanasia. To maintain the hormonal patterns and the social and behavioral dynamics, surgical infertilization preserving the gonads (i.e., salpingectomy and vasectomy) is recommended. Mini-invasive surgery is an eligible choice when dealing with wildlife, allowing reduced captivation time. For these reasons, 77 free-ranging nutrias, captured in urban nuclei in Italy, underwent infertilization under general anesthesia; laparoscopic salpingectomy and vasectomy were performed on 32 animals and traditional surgery on the remainder, leaving the gonads in place. A three-port technique was used, with two paramedian trocars (5 mm) for the instruments and a median one for the telescope. Ablation was obtained through Onemytis plasma device, allowing a rapid surgical time with no need to place visceral sutures; the skin was surgically closed. After recovery, the animals were released, and no overt complications were noted. No modification of the behavioral patterns was noted, and the population decreased during the following months.
麝鼠（）是一种外来入侵物种，在欧洲广泛传播。根据欧盟第1143/2014号法规，麝鼠需接受管理计划以减少其扩散。手术绝育控制被认为是一种可接受的方法，特别是在城市环境中，可避免安乐死。为维持激素水平以及社会和行为动态，建议采用保留性腺的手术绝育方法（即输卵管切除术和输精管切除术）。在处理野生动物时，微创手术是一个合适的选择，可减少捕获时间。基于这些原因，在意大利城市核心区域捕获的77只野生麝鼠在全身麻醉下接受了绝育手术；32只动物接受了腹腔镜输卵管切除术和输精管切除术，其余动物接受了传统手术，保留性腺。采用三孔技术，两个旁正中套管针（5毫米）用于器械操作，中间一个用于放置腹腔镜。通过Onemytis等离子设备进行消融，手术时间短，无需进行内脏缝合；皮肤进行手术缝合。恢复后，动物被放归自然，未发现明显并发症。行为模式未发生改变，且在接下来的几个月里种群数量有所减少。
